How does Biometric Payment Work? A Step-by-Step Guide
Biometric payment typically involves the following steps:
STEP 1: Registering Biometric Data
The process begins with the user registering their biometric data, such as a fingerprint or facial scan, with the payment provider. This data is securely stored for future use.
STEP 2: Providing Biometric Input
When making a payment, the user provides their registered biometric trait, such as scanning their fingerprint or using facial recognition at a scanner or camera.
STEP 3: Verifying Identity
The system compares the captured biometric data to the stored template using advanced algorithms, ensuring the identity verification is accurate and secure.
STEP 4: Processing the Payment
After successful identity verification, the payment is authorized, and the linked payment method, such as a bank account or credit card, is charged.
STEP 5: Confirming the Transaction
The user receives confirmation of the completed transaction, either as a digital notification or a physical receipt.
Types and Methods of Biometric Payment Systems
There are several types of biometric authentication methods used in biometric payment systems:
1. Fingerprint Recognition
This method captures the unique patterns of ridges and valleys on a user’s fingertip to verify their identity. It is one of the most widely used and reliable forms of biometric authentication, commonly found in smartphones and payment terminals.
2. Facial Recognition
Facial recognition analyses distinct features of a user’s face, such as the distance between the eyes or the shape of the jawline, to authenticate payments. It is increasingly popular in mobile payment apps and offers a quick, contactless payment experience.
3. Iris or Retina Recognition
Iris and retina scanners identify users by analysing the unique patterns in their eyes. While highly accurate, this method is less common in everyday payment systems due to the need for specialized hardware.
4. Voice Recognition
Voice recognition uses the unique characteristics of a person’s voice—such as pitch, tone, and cadence—to authenticate payments. It is often employed in hands-free or phone-based payment scenarios, like drive-throughs or virtual assistants.
5. Vein Recognition
This method maps the unique vein patterns in a user’s palm or finger for identification. Vein recognition is highly secure since vein patterns are nearly impossible to replicate and can only be captured from a live person.
6. Signature Recognition
Signature recognition analyses a user’s handwritten signature, focusing on details such as pressure, speed, and stroke order. Although less common, it is still used in certain payment systems where physical or digital signatures are required.
